[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley with a pipe protection frame for mounting an engine.

[0002]

[Prerequisite structure] As shown in Fig. 5, for example, the bogie with an engine mounting pipe protection frame according to the present invention is assumed to have the following premise structure. That is, the pipe 1 is framed in a box shape to form a box-shaped pipe protection frame 2. Lower left and right frames 3a located on the left and right sides of the lower part of the pipe protective frame 2
A horizontal underframe 4 for supporting the device is mounted between the 3b.
Then, a pair of left and right wheels 5a and 5b is arranged near the left and right ends of the horizontal frame 4.

[0003]

2. Description of the Related Art In the above premise structure, each wheel 5a
As a structure for detachably attaching 5b to the pipe-made protective frame 2, there is a structure shown in FIGS. 5 and 6 in the prior art.
That is, the axle 16 runs parallel to the underside frame 4 via the bearing plate 15 and is fixed by the shaft retainer 17, the bolt 18, and the nut 19. The wheel pivot shaft portions 6a and 6b at the left and right ends of the axle 16 pass under the lower left and right frames 3a and 3b and protrude laterally outward. And the lower left and right frames 3a
On the lateral outer side of 3b, the wheels 5a and 5b are rotatably supported on the wheel pivot shafts 6a and 6b, and are retained by the retaining ring 20.

[0004]

The above prior art has the following problems. (A) Since the horizontal frame 4 is located higher than the axle 16,
The ground height of the engine 10 supported on the horizontal frame 4 is increased, and the horizontal swing of the bogie due to the horizontal vibration component of the engine 10 is large. (B) Since the lower left and right frames 3a and 3b are positioned higher than the axle 16, the height of the bogie is increased. Moreover, since the axle 16 protrudes laterally outward, the width of the bogie is increased. (C) To pivotally support the wheels 5a and 5b,
The required structure of the bearing plate 15 and the shaft retainer 17 makes the structure complicated and heavy. It is an object of the present invention to reduce the rolling of the bogie due to engine vibration, to reduce the size of the bogie, and to simplify the structure for pivoting the wheels.

[0005]

In order to achieve the above object, the present invention is configured as follows, for example, as shown in FIGS. The pipe (1) is framed in a box shape to form a box-shaped pipe protection frame (2), and lower left and right frames (3a) (3) located on the left and right sides of the lower portion of the pipe protection frame (2).
b) A horizontal underframe (4) for supporting the equipment is mounted between them, and a pair of left and right wheels (5) are mounted near the left and right ends of the horizontal underframe (4).
a) In a bogie equipped with an engine mounting pipe protective frame configured by disposing (5b), the horizontal frame (4) is formed in a straight line, and is mounted on the horizontal frame (4) via a vibration isolating means (12). To support the engine (10), and attach the left and right frame ends (4a) (4b) of the horizontal frame (4) to the left and right lower frames (3a) (3b) of the left and right pipe protection frames (2). Inside
And fixed to the same height as the left and right lower left and right frames (3a) (3b),
Connect each frame end (4a) (4b) of the horizontal frame (4) to the wheel pivot shaft (6a) (6
b) is also used, and a pair of left and right wheels (5a) (5b)
Is composed of a pair of semi-circular wheel halves (7a) and (7b) fixed by a fixing means (8) in a state of being connected in a circular shape, and the inside of the lower left and right frames (3a) (3b). And the wheel pivot (6a)
A pair of left and right wheels (5a) (5b) are fixed by a fixing means (8) in a state where a pair of wheel half bodies (7a) and (7b) are connected in a circle so as to sandwich (6b). Are rotatably supported on the respective wheel pivot shafts (6a) (6b) of the horizontal frame (4).

[0006]

[Operation and effect of the present invention] The trolley with a pipe protection frame for mounting an engine according to the present invention has wheels (5a) (5
b) is attached. That is, the frame end (4a) of the horizontal frame (4)
The wheel pivot shafts (6a) (6b), which are also used as (4b), are sandwiched between a pair of wheel halves (7a) (7b). And the wheel half (7a)
(7b) is connected to each other in a circular shape, and then fixed by fixing means (8). This allows the wheels (5a) (5b)
Is rotatably supported by the wheel pivot shafts (6a) and (6b) in a state of entering the inside of the pipe protection frame (2). By attaching the wheels (5a) and (5b) in this manner, the present invention operates as follows. That is, when the wheels (5a) and (5b) enter the inside of the pipe protective frame (2), the wheels (5a) and (5b)
Are guarded by the lower left and right frames (3a) and (3b) of the pipe protective frame (2). In addition, both ends of the horizontal frame (4) are fixed to the lower left and right frames (3a) and (3b) of the pipe protective frame (2), respectively, so that the wheels (5a) and (5b) are fixed. The pivoted wheel pivot shafts (6a) (6b) are supported in a double-supported state. And since it acts as mentioned above, this invention has the following effects. (A) Since the wheel support shaft portion for supporting the wheels is formed by using the horizontal support frame for device support as it is, there is no need to separately provide a member for supporting the wheels. Therefore, the structure of the truck can be simplified accordingly, and the manufacturing cost can be reduced. (B) Since the wheel pivot shaft portion is inside the lower left and right frames of the pipe-made protective frame, the wheels do not enter the pipe-made protective frame and do not protrude laterally from the pipe-made protective frame, and the width of the bogie. Can be reduced. In addition, the side surfaces of the wheels are guarded by the lower left and right frames of the protective frame made of pipes, and other objects come into contact with the side surfaces of the wheels when the bogie is moved, without having to provide additional members for guarding the wheels. To protect the wheels from damage. (C) Since both ends of the horizontal frame are fixed to the lower left and right frames of the protective frame made of pipe, respectively, the wheel pivot shafts, which are also used as both frame ends of the horizontal frame, have both ends. It is firmly supported in the state. Therefore, even if an impact is applied to the wheel attached to the wheel pivot shaft, the wheel pivot shaft is unlikely to bend and the durability of the wheel pivot shaft against the impact can be maintained high.
